Step‑by‑Step Instructions for Peanut Butter Oatmeal Monster Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your Peanut Butter Oatmeal Monster Cookies will bake evenly and acquire that perfect golden hue. While the oven heats up, prepare your baking sheets by lining them with parchment paper. This will prevent the cookies from sticking and make cleanup a breeze.
Step 2: Cream the Wet Ingredients
In a mixing bowl, combine ½ cup of softened unsalted butter, ½ cup of granulated sugar, ½ cup of light brown sugar, and ½ cup of creamy peanut butter. Beat the mixture with an electric mixer on medium speed until it becomes smooth and fluffy, which should take about 2-3 minutes. The mixture will be light in color and creamy, creating a perfect base for your cookie dough.
Step 3: Incorporate the Egg and Vanilla
Add 1 room-temperature egg and 1 teaspoon of pure vanilla extract to your creamed mixture. Use the mixer to beat all these ingredients together until well combined, ensuring the egg is fully integrated and the mixture is smooth. This step adds moisture and enhances the flavor of your Peanut Butter Oatmeal Monster Cookies.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, 1¼ cups of old-fashioned rolled oats, ¼ teaspoon of salt, ½ teaspoon of baking powder, and ½ teaspoon of baking soda until evenly combined. This ensures that your dry ingredients are well-distributed, which is vital for creating well-textured cookies that rise beautifully.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture while mixing on low speed. Continue to mix until just combined, being careful not to overmix. The dough should be thick and well blended—this is the foundation for your delicious Peanut Butter Oatmeal Monster Cookies.
Step 6: Fold in the Add-Ins
Carefully fold in ¾ cup of colorful M&Ms and ½ cup of semi-sweet chocolate chips using a spatula. This gentle motion preserves the airiness of the dough while ensuring the candies are evenly distributed throughout the cookie mix, adding delightful pops of color and sweetness to each bite.
Step 7: Chill the Dough (Optional)
If you prefer thicker cookies, you can refrigerate the dough for about 30 minutes. Chilling allows the flavors to meld and can prevent the cookies from spreading too much during baking. However, if you’re in a hurry, you can skip this step and proceed to baking.
Step 8: Scoop the Cookie Dough
Using a cookie scoop or two tablespoons, drop spoonfuls of dough onto the prepared baking sheets, spacing them about 2 inches apart. This will give the cookies room to spread as they bake, ensuring they don’t merge into one giant cookie.
Step 9: Bake the Cookies
Place the baking sheets in the preheated oven and bake for about 12 minutes, or until the edges are lightly golden brown while the centers still appear soft. Keep an eye on them, as you want that ideal chewy texture in the Peanut Butter Oatmeal Monster Cookies.
Step 10: Cool and Enjoy
Once baked, let the cookies rest on the baking sheets for 5 minutes. This allows them to firm up slightly before transferring them to wire racks to cool completely. Once cooled, store your delicious cookies in an airtight container, or enjoy them warm for a delightful treat!
Make Ahead Options
These Peanut Butter Oatmeal Monster Cookies are a delightful choice for meal prep! You can prepare the cookie dough up to 24 hours in advance by following the recipe steps up to scooping. Simply cover the bowl with plastic wrap and refrigerate to maintain freshness. For additional convenience, you can also portion out the dough into individual scoops on a lined baking sheet, freeze them for up to 3 months, and bake straight from the freezer, adding an extra minute or two to the baking time. This planning allows you to enjoy fresh, warm cookies with minimal effort, perfect for busy weeknights when cravings hit!

Expert Tips for Peanut Butter Oatmeal Monster Cookies
Perfect Butter Temperature: Ensure your butter is softened to room temperature for easy creaming. This prevents the cookies from spreading too thin when baked.
Don’t Overmix: Mix the dough until just combined. Overmixing can lead to tough cookies instead of the desired chewiness and flavor balance.
Chilling the Dough: For thicker cookies, chill the dough for about 30 minutes before baking. This helps them hold their shape better in the oven.
Testing Freshness: Always check that your baking powder and baking soda are fresh. Expired leavening agents can result in flat cookies that fail to rise.
Customizing Add-ins: Feel free to substitute mix-ins like nuts or different flavored chips for a personalized touch. Just keep the balance of flavors in mind when using the Peanut Butter Oatmeal Monster Cookies recipe.
Storage Tips for Peanut Butter Oatmeal Monster Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 5 days to maintain their chewy texture. Make sure to separate layers with parchment paper to avoid sticking.
Freezer: Freeze cookies in a single layer on a baking sheet before transferring them to a zip-top bag. They can last for up to 3 months, ready to satisfy your sweet tooth anytime!
Reheating: To enjoy warm cookies, pop them in the microwave for about 10-15 seconds. This revives the gooeyness, especially with those delightful M&Ms and chocolate chips.
Dough Storage: If you want to prepare ahead, freeze the cookie dough in scooped portions. Bake directly from the freezer, adding an extra 1-2 minutes to the baking time for fresh Peanut Butter Oatmeal Monster Cookies.

Peanut Butter Oatmeal Monster Cookies Recipe FAQs
What type of peanut butter should I use?
I recommend using creamy peanut butter for the best texture and flavor. If you or someone you’re baking for has nut allergies, sunflower seed butter works perfectly as a nut-free substitute without compromising the taste!
How long do Peanut Butter Oatmeal Monster Cookies last?
These cookies will stay fresh in an airtight container at room temperature for up to 5 days. For extended storage, consider freezing them, where they can last for up to 3 months without losing their chewy goodness.
Can I freeze the cookie dough?
Absolutely! To freeze, scoop the dough into individual portions and place them on a baking sheet until firm. Transfer the frozen dough balls to a zip-top bag. When you’re ready to bake, simply preheat the oven and bake directly from frozen, adding an extra 1-2 minutes to the baking time.
What if my cookies are spreading too much while baking?
To prevent spreading, make sure your butter is at the right temperature—softened, not melted. If you find they spread too thin, try chilling the dough for about 30 minutes before baking. This helps maintain their shape!
Are there any allergen considerations?
Yes! If you’re making these cookies for someone with allergies, substitute the peanut butter with sunflower seed butter and ensure your chocolate chips and other add-ins are allergen-free. Always double-check labels to ensure safety!
How can I ensure my cookies maintain their chewy texture?
To keep your Peanut Butter Oatmeal Monster Cookies chewy, don’t overmix the dough, and make sure to bake them until just golden on the edges while remaining soft in the middle. Allowing them to cool on the baking sheet for a few minutes before transferring them to a wire rack helps them set perfectly!
